Phantom EFX and independent game development studio 8monkey Labs announced today the availability of a series of updates to their first-person shooter, Darkest of Days. PC players are now able to use 8monkey’s own level editing software, Habitat, to create their own levels in which to wreak havoc. Phantom EFX also released an Instant Action gameplay update that will allow players to choose their favorite weapons and travel back to their favorite missions with a weapon set of their choosing.

The release of Habitat allows PC gamers to create their own Darkest of Days mods, and even unlocks shader code, so graphical mods are also a possibility. The patch also addresses some consumer demands, including: support for fourth and fifth mouse buttons, a mouse smoothing option, fixes for hardware specific OpenAL and ATI crashes, and new PhysX system software.
